In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, liquid biomolecular condensates, and some cutting fluids for metal working. Two liquids can form different types of emulsions. As an example, oil and water can form, first, an oil-in ...
An emulsion semisolid dosage form used for external application on the skin. There are two forms of cream, including oil-in-water cream with water as the continuous phase and water-in-oil cream with oil as the continuous phase [17] Contains >20% water and volatiles and/or <50% of hydrocarbons, waxes, or polyethylene glycols as the intermedia [18]
Creaming, in the laboratory sense, is the migration of the dispersed phase of an emulsion under the influence of buoyancy.The particles float upwards or sink depending on how large they are and density compared to the continuous phase as well as how viscous or how thixotropic the continuous phase might be.
This rule states that the phase which the emulsifier is the most soluble in will be the continuous phase, even if it has a smaller volume fraction overall. For example, a mixture that is 60% Water and 40% Oil can form an emulsion where the water is the dispersed phase and the oil is the continuous phase if the emulsifier is more soluble in the oil.
In all of the typical emulsions, there are tiny particles (discrete phase) suspended in a liquid (continuous phase). In an oil-in-water emulsion, oil is the discrete phase, while water is the continuous phase. What the Bancroft rule states is that contrary to common sense, what makes an emulsion oil-in-water or water-in-oil is not the relative ...
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
Oil-in-water emulsified fuels, such as the Orimulsion system and bitumen emulsions, are examples of water-continuous systems. These emulsions are often considered high internal phase emulsions (HIPE) because the continuous phase makes up about 30% of the fuel composition, whereas the dispersed phase is usually the minor component.
A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). The dispersed phase particles have a diameter of approximately 1 nanometre to 1 micrometre. [2] [3] Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid.
